Hi
Currently we have just a few car-branded models supported. All are listed here: http://www.gps-data-team.com/gps-poi.php Unfortunately, the Fiat brand is not on the list. You can try to use a generic Garmin GPI or GPX format.

We can add Fiat to the list of supported brands. I was hoping someone would come with a simple answer. We contacted a few Fiat dealers to find the right answer for you, but no joy.

The name for the folder and sub folder are critical and you must use a USB stick, NOT SD card.
Both the folders names are critical and it only works with a USB Stick with nothing else on it.
I tried with a SD card and it did not work.
